1 TV won't turn on, stand-by LED blinking same as backlight
Hi,
I've bought this unit with some as i thought small failure. When I plug it to socket it starts turning on and off every couple of second, almost same frequency as samsung logo on bottom of screen. While turning on screen backlight turning on and after 1 or 2 seconds off.
I thought like most of cases with "flat TV" it's power supply board. So I've ordered one, second hand, checked, tested with warranty. Today I've put it in my TV and there is still same story. Only one change is (I think) backlight is brighter on new board than on old one.
Do anybody have any clue what can happen? Previous owner told me that TV stops working by its own. One day he watched TV and was fine, next day want to turn it on and nothing happen.
Thank you in advance for any help
Kind regards
Kriss
Is this a good question?

Kri Ss just to clarify. WIth the new power board the TV turns on and off and on again by itself? The Samsung logo does the same or does it stay lit?

Hi, thank you for your answer. Maybe it will be easier if I paste videos links.
This video is with my old power board https://youtu.be/z4YYRzqMnUo

Samsung logo on bottom of tv getting dimmer when backlight turning on, and brighter when tv getting off.
In this time nothing appears on the screen
